My bot found errors running 'make dt_binding_check' on your patch:

yamllint warnings/errors:

dtschema/dtc warnings/errors:
Documentation/devicetree/bindings/usb/microchip,sama7g5-tcpc.example.dt.yaml:0:0: /example-0/tcpcb@e0844000: failed to match any schema with compatible: ['microchip,sama7g5-typec']

See https://patchwork.ozlabs.org/patch/1459823

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit.
